How can we save mother earth?

Agriculture is a very important sector that helps alleviate
hunger and poverty. It is also essential for the development of a
country, but unfortunately people are using some very poor
practices which is destroying our mother earth.

Land transformation, the use of land to yield goods and services,
is the most substantial way humans alter the Earth's ecosystems,
and is considered the driving force in the loss of biodiversity.
Estimates of the amount of land transformed by humans vary from
39 to 50%. Land degradation, the long-term decline in ecosystem
function and productivity, is estimated to be occurring on 24% of
land worldwide, with cropland overrepresented. The UN-FAO report
cites land management as the driving factor behind degradation
and reports that 1.5 billion people rely upon the degrading land.
Degradation can be deforestation, desertification, soil
erosion, mineral depletion, or chemical degradation (acidification and salinization).

Agriculture accounts for 70% of withdrawals of freshwater
resources. Agriculture is a major draw on water from aquifers, and currently draws from these
underground water sources at an unsustainable rate. It is long
known that aquifers in areas as diverse as northern China, the
Upper Ganges and the western US are being
depleted, and new research extends these problems to aquifers in
Iran, Mexico and Saudi Arabia. Increasing pressure is being
placed on water resources by industry and urban areas, meaning
that water scarcity is increasing and agriculture is
facing the challenge of producing more food for the world's
growing population with fewer water resources. Agricultural water
usage can also cause major environmental problems, including the
destruction of natural wetlands, the spread of water-borne
diseases, and land degradation through salinization and
waterlogging, when irrigation is performed incorrectly.

So from this article we see that there is still a lot we have
to do to save our dying mother earth.
